Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional cogwheel transmission is used, then power transmission is reliable, but versatility in providing variable ratios and directional conversions is limited
Solution Approach 1:
The transmission system is divided into multiple independent rotors, each capable of receiving power from the drive shaft and transmitting to driven shafts independently. This segmentation allows flexible combination of rotors to achieve different transmission ratios and directional conversions without requiring complex gear trains
Solution Approach 2:
Each rotor is designed with multiple arms that can engage with levers on different driven shafts, allowing a single rotor to perform multiple transmission functions. The system can provide both rotary-to-rotary and rotary-to-linear motion conversion through the same basic rotor structure, enhancing versatility without increasing overall system complexity
2Productivity
If centrifugal impact mechanism is used, then efficiency in converting rotary motion to linear motion is improved, but device complexity increases due to additional components
Solution Approach 1:
The arms are connected to rotors through joints that allow dynamic movement, enabling the arms to swing outward during rotation and generate impact forces. This dynamic configuration allows the system to convert rotary motion to linear impact motion efficiently while keeping the structural complexity manageable through standardized joint designs
Solution Approach 2:
Levers serve as intermediary elements between the arms and driven shafts, translating the impact forces from rotating arms into useful work on the driven shafts. The one-way clutch mechanism on levers acts as a mediator that allows motion transmission in the desired direction while preventing reverse motion, improving conversion efficiency without requiring complex locking mechanisms
3Ease of operation
If one-way clutch is used on levers, then directional control is achieved, but loss of time occurs during engagement and disengagement
Solution Approach 1:
The one-way clutch mechanism on levers is designed to maintain continuous engagement during the power transmission cycle, allowing smooth directional control without repeated disengagement and re-engagement. The clutch allows free motion in the driving direction while automatically preventing reverse motion, eliminating time losses associated with manual clutch operation
